You can download the ISO from their download site and install it onto a new machine. Unfortunately, because it’s still a BETA product there is no upgrade path from 3.4. I’d expect this to change in the near future.

The latest release of Proxmox VE has entered it’s first BETA today with the release of Proxmox VE 4.0 BETA 1.

This is a very welcome addition to any small Proxmox Cluster.
